An official told CNN that painkillers likely factored into Prince's health scare aboard a flight on his private jet just days before his death. The jet made an emergency landing in Illinois, where doctors treated him for a possible overdose, the source told CNN.

Prince was found dead at his Chanhassen, Minnesota, home last Thursday. He was 57.
